How did you update to the latest LW? Did you use your Pro personal download page??

Open your LW & click on Help > about LW...does it say you're using a Pro version?

Pro used to entitle you to 6 months of free updates (they've just recently added the option of buying Pro for a year), so if you bought your Pro more than 6 months ago then you'll have to pay again to get an up to date Pro
